Inset cross cutting knife refers to the knife edge inset high speed steel HSS, the knife body uses the grinding tool steel SKD11, heat treatment grinding out the knife edge use, HRC60-63 degrees, different high speed steel HRC is not the same, this kind of blade is generally high service life, we all know high speed steel hardness high toughness, suitable for high-speed cutting, even cutting some high precision materials are comfortable, The incision is smooth and smooth without burr, durable.
